Starting with SCOPe version 2.01, data from all versions of
SCOPe, SCOP, and Astral since 1.55 are stored
in a relational database.

Note that we have removed the astral_seq_blast*
tables from the download, since these tables are so large. They are available on request.
Since SCOP release 1.55, the
SCOP classification has
been distributed in the form of a
set of sequences, coordinates, and parseable files, all based on a
new set of identifiers.
For an account of these changes, file
formats, file contents and meaning, see the Lo Conte et al (2002)
